WASHINGTON, DC (April 9, 2013)—A variety of mutations may give rise to breast cancer, but scientists generally assume that it starts off with just a few. That’s because later-stage breast cancers tend to have more mutations—they are more heterogeneous—than early stage cancers. Now, new findings by scientists at Fox Chase Cancer Center demonstrate heterogeneity is prevalent even within legions of ductal carcinoma in situ (DCIS), the most common, earliest stage non-invasive breast cancer (stage 0).

WASHINGTON, DC (April 9, 2013)—Researchers from Fox Chase Cancer Center have found that omega-3 fatty acids and their metabolite products slow or stop the proliferation, or growth in the number of cells, of triple-negative breast cancer cells more effectively than cells from luminal types of the disease. The omega-3s worked against all types of cancerous cells, but the effect was observed to be stronger in triple-negative cell lines, reducing proliferation by as much as 90 percent. The findings will be presented at the AACR Annual Meeting 2013 on Tuesday, April 9.

WASHINGTON, DC (April 9, 2013)—A new preclinical technology enables researchers to quickly determine if a particular treatment is effective against gastrointestinal stromal tumors (GISTs), providing a boost to animal research and possibly patient care, according to new findings presented by Fox Chase Cancer Center at the AACR Annual Meeting 2013 on Tuesday, April 9.

WASHINGTON, DC (April 9, 2013)—Researchers at Fox Chase Cancer Center have identified a host of small molecules critical to metabolism in cells of triple-negative breast cancer—one of the least understood groups of breast cancer. These molecules, called metabolites, include key players in energy regulation and lipid synthesis. They could help pave the way for helping researchers differentiate among different forms of the disease and ultimately point to new targets for treatment.

WASHINGTON, DC (April 8, 2013)—Once considered part of the “junk” of our genome, much of the DNA between protein-coding genes is now known to be transcribed. New findings by scientists at Fox Chase Cancer Center have identified several dozen transcripts known as lincRNAs, or long intergenic non-coding RNAs, that are dysregulated in breast cancer.

WASHINGTON, DC (April 7, 2013)—Colorectal cancer is the second leading cause of cancer-related deaths in the United States. Once colorectal cancer has spread to other parts of the body, only 11 percent of patients will survive five years from the date of their diagnosis. Most colorectal cancers are adenocarcinomas—cancers that begin in cells that make and release mucus and other fluids. Adenocarcinomas begin as benign tumors called adenomas, which become malignant over time.

WASHINGTON, DC (April 7, 2013)—Women with HIV acquire cancer-causing forms of the human papillomavirus (HPV) that are not included in the current HPV vaccines Gardasil and Cervarix, according to new research from Fox Chase Cancer Center being presented at the AACR Annual Meeting 2013 on Sunday, April 7.

"People with issues in their immune system such as HIV will be at risk of acquiring HPV, as well – and the current vaccine may not fully protect them," says study author Elizabeth Blackman, MPH, research specialist at Fox Chase.

PHILADELPHIA (March 25, 2013)—The American Association for Cancer Research will inaugurate the first class of the Fellows of the AACR Academy at the AACR Annual Meeting 2013, held in Washington, D.C., April 6-10. Inductees include Beatrice Mintz, PhD, and Alfred G. Knudson Jr., MD, PhD.
